WebPipelined Datapath The goal of pipelining is to allow multiple instructions execute at the same time We may need to perform several operations in a cycle Increment the PC and add registers at the same time. Fetch one instruction while another one reads or writes data. Thus, like the single-cycle datapath, a pipelined processor needs Webper instruction, which fixes some shortcomings of the 1-cycle implementation. • Faster instructions (R-type) are not held back by the slower instructions (lw, sw) • The clock cycle time can be decreased, i.e. faster clock can be used • Eventually simplifies the implementation of pipelining, the universal speed-up technique. east west bank main office address
